Hi,
i have tried this too, but it gave me another error
message: AttributeError
<dtml-var "PARENTS[-1].GuestBook.addEntryAction">
what am i doing wrong?
Ah. addEntryAction is a method, not a property. When calling a method in
Python (and this is a Python expression, BTW), you need to call it like
this:

<dtml-var "PARENTS[-1].GuestBook.addEntryAction()">

Depending on the method in question, you may need to supply arguments as
well:

<dtml-var "PARENTS[-1].GuestBook.addEntryAction(arg1='value1',
arg2='value2')">

I'd like to point out that it is generally a *very bad idea* to be using
DTML for application logic like this. You would be better off switching
to a combination of Python Script objects and DTML, or Python Scripts
and ZPT.
